Benzotrichloride (BTC), also known as α,α,α-trichlorotoluene, phenyl chloroform or (trichloromethyl)benzene, is an organic compound with the formula C 6 H 5 CCl 3. Benzotrichloride is an unstable, colorless or somewhat yellowish, viscous, chlorinated hydrocarbon with a penetrating odor.
According to Ogawa and Curran, trifluorotoluene is similar to dichloromethane in standard acylation, tosylation, and silylation reactions. [4] The dielectric constants for dichloromethane and trifluorotoluene are 9.04 and 9.18, respectively, indicating similar solvating properties.
In 40 CFR 156.62, the EPA established four Toxicity Categories for acute hazards of pesticide products, with "Category I" being the highest toxicity category (toxicity class).
Pharmacotoxicology entails the study of the consequences of toxic exposure to pharmaceutical drugs and agents in the health care field. The field of pharmacotoxicology also involves the treatment and prevention of pharmaceutically induced side effects.
Assignment to a toxicity class is based typically on results of acute toxicity studies such as the determination of LD 50 values in animal experiments, notably rodents, via oral, inhaled, or external application.
Modes of toxic action are important, widely used tools in ecotoxicology and aquatic toxicology because they classify toxicants or pollutants according to their type of toxic action. There are two major types of modes of toxic action: non-specific acting toxicants and specific acting toxicants.
This is the list of extremely hazardous substances defined in Section 302 of the U.S. Emergency Planning and Community Right-to-Know Act (42 U.S.C. § 11002).The list can be found as an appendix to 40 CFR 355. [1]
Benzoyl chloride is produced from benzotrichloride using either water or benzoic acid: [2] C 6 H 5 CCl 3 + H 2 O → C 6 H 5 COCl + 2 HCl C 6 H 5 CCl 3 + C 6 H 5 CO 2 H → 2 C 6 H 5 COCl + HCl. As with other acyl chlorides, it can be generated from the parent acid and standard chlorinating agents such as phosphorus pentachloride, thionyl ...
